Cytotoxic activity of flavone glycoside from the stem of Indigofera aspalathoides Vahl

A novel flavone glycoside has been isolated from the stem of Indigofera aspalathoides, and its structure was identified by colour reactions and spectral analysis. The isolated compound was tested for cytotoxic activity against 57 human tumour lines representing leukemia, non-small cell lung, colon, central nervous system, melanoma, ovarian, renal, prostate and breast cancers. The results showed that the flavone glycoside has cytotoxic activity against human tumour cell lines.
